LIQUID-TRANSFERRING DEViCE FOR VESSELS.

SPECIFICATION forming part of Letters Patent No. 466,336, dated January5, 1892.

Application filed October 24, 1890. Serial No. 369,170. (No model.)

To all whom it may concern:

Be it known that I, EDWARD A. FRANKLIN, of Brenham, in the county ofWashington and State of Texas, have invented a new and usefulImprovement in Liquid-'lransferri ng Devices, of which the following isa full, clear,

and exact description, reference being bad to the accompanying drawing,forming part of this specification, in which the figure is a sideelevation, partly in section, showing my improved apparatus in positionfor transferring liquid from one vessel to another.

In transferring liquids which have become stratified it is oftendesirable to transfer one or more strata from one vessel to anotherwithout disturbing the other strata, or where the liquid is gaseous orvolatile it may be desirable to transfer the liquid Without the escapeof gas or vapor which may have formed in the upper part of the vessel,as in filling a vessel or lamp with petroleum oil or gasoline at night.To this end I have designed my improvement, which I will now proceed todescribe, so that others skilled in the art may manufacture and use thesame. I

In the drawing, a represents an oil-can or other liquid-reservoir havinga screw top orcap I), through which passes a curved pipe or tube 0,formed of tin, glass, or other suitable material,

the joint between the screw-capand pipe be ing preferably rendered tightby solder or suitable packing. This pipe 0 extends downward outside ofthe vessel a, below the bottom of the same, or preferably is providedwith an extension-tube c, formed of india-rubber or other suitablematerial. Inside of the vessel a, fitting telescopically on the tube 0,is an extension-pipe d, the position of which may beregulated, eitherbefore the screw-cap is put on the vessel or afterward, by means of therod e, which is secured to a collar on the tube d and extends upwardthrough an aperture or stuffing-box in the cap I). Passing through thecapbis an air-tube f, which opens inside the vessel a at the topthereof, and is connected directly or by a tube g, formed of rubber orother suitable material, with a rubber air-compressing bulb h or othersuitable The operation is as follows: The tube 61 is adjusted and thecap b is tightly fitted on the bulb 72 air is forced into the vessel a,which starts a current of liquid through the pipes c c, and the currentcontinues as long asdesired,owing to the siphon action of the tubes.Where the receiving-receptacle, however, is situate above the level ofthe liquid in the vessel a, the current may be maintained by repeatedcompressions of the bulb h. My improvement is also adapted to use inchemical fire-extinguishers, especially Where there is apt to be asediment in the bottom of the vessel. In this case the tube 0 isprovided with a stop-cock 70, which is allowed to remain closed untilthe required amount of air is compressed in the upper part of the vesselby means of the air-compressor h. The tube d is adjusted above thesediment, and until the pressure of air is sufficient to cause a jet ofliquid of the desired strength the stop-cock is allowed to remainclosed. The main advantage of my improvement, however, is a cap for cansand vessels provided with an airforce supply-pipe and adelivery-pipe,where-s by the liquid canbe transferred from one vesselto'another without the escape of noxious gases or the disturbance ofdiiferent strata.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s-

1. As a new article of manufacture, a cap for vessels, having'anair-supply pipe and an adjustable delivery-pipe, the inner section ofsaid delivery-pipe being adjustable in length and the outer sectionbeing of greater length than suchinner section, and a rod passingthrough the cap and attached to the adjustable portion of thedelivery-pipe; substantially as described.

2. As a new article of manufacture, a cap for vessels, a delivery-pipe,and an air-supply pipe passing through said cap,

the inner sec tion of said delivery-pipe being adjustable in ing throughsaid cap and attached to the ad- IO length and the outer section beingof greater justable portion of said delivery-pipe, sublength than suchinner section and provided stantially as described. with a stop-cock,and a rod passing through In testimony whereof I have hereunto set 5 thecap and attached to the adjustable pormyhand this 29thdayofSeptember,A.D.1890.
